> Key: FLINK-41341
> URL: https://issues.apache.org/jira/browse/FLINK-41341
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / API, Table SQL / Runtime
> Reporter: Ramin Gharib
> Assignee: Ramin Gharib
> Priority: Major
>
> {code:sql}
> VARIANT_ARRAY_APPEND(variant, path, value) -- VARIANT
> VARIANT_ARRAY_APPEND(v, '$.items', 'x')
> --
> {"coupon":null,"items":[{"qty":2,"sku":"A1"},"x"],"order_id":17,"user":{"email":"[email protected]","name":"ada"}}
> {code}
> Scope:
> * An array value is added as one nested element.
> * A missing path is ignored. A target that is not an array fails, and
> TRY_VARIANT_ARRAY_APPEND returns NULL instead.
> * A SQL NULL argument gives NULL.
> * Table API and PyFlink expressions, SQL and Table API tests, docs.
> Depends on FLINK-41338
